Higgins Clark Mary. Where Are You Now?

It has been ten years since 21-year-old Kevin MacKenzie, Jr. ("Mac"), has been missing. A Columbia University senior, about to graduate and already enrolled in Duke University Law School, he walked out of his room in Manhattan 's Upper West Side without a word to his college roommate and has never been seen again. However, he does make three ritual phone calls to his mother every year: on her birthday, on his birthday, and on Mother's Day. Each time, he assures her he is fine, refuses to answer her frantic questions, then hangs up.
